HT1926 itunes entry point not found?

keep seeing these error messages, i tunes won't open. have re-installed several times.
itunes.exe - entry point not found. the procedure entry point AVCFAssetCreateWithByteStreamAndOptions could not be located in the dynamic link library AVFoundationCF.dll.
itunes was not installed correctly. Please reinstall itunes. error 7 (windows error 127)

"The procedure entry point AVCPlayerAppliesMediaSelectionCriteriaAutomaticallyKey could not be located in the dynamic link library AVFoundationCF.dll"
Some progress on this  error, j.
That one can be produced if you have an older version of Apple Application Support on the PC than is required by iTunes version 11.1.4.62. (The required version of Apple Application Support is included in the standard iTunes installers, but for some reason it hasn't been updating properly for some folks.)
Let's try updating your Apple Application Support to version 3.0 by doing a standalone Apple Application Support install.
Download and save a copy of the iTunesSetup.exe (or iTunes64setup.exe) installer file to your hard drive:
http://www.apple.com/itunes/download/
Download and install the free trial version of WinRAR:
http://www.rarlab.com/download.htm
Right-click the iTunesSetup.exe (or iTunes64Setup.exe), and select "Extract to iTunesSetup" (or "Extract to iTunes64Setup"). WinRAR will expand the contents of the file into a folder called "iTunesSetup" (or "iTunes64Setup").
Go into the folder and doubleclick the AppleApplicationSupport.msi to do a standalone AAS install.
Does it install properly for you? If so, can you launch iTunes without the error now?
If instead you get an error message during the install, let us know what it says. (Precise text, please.)

    Why is my itunes not installing properly?
    I installed itunes day before yesterday,  I spent hours last night linking all my music photograph and movie files, its a new windows 8 laptop.
    I plugged in my 64GB ipad 3 rebooted it and reloaded all the information I wanted on it, took hours... finally completed this this morning. After this I restarted the laptop to configure my icloud link for the laptop (which I installed last night while I was loading files, I chose to restart later)
    on completion I turned my laptop off for a few hours, when I turned it back on I went to itunes to connect my iphone to do the same and I got this message:
    iTunes exe - Entry Point Not Found
    The procedure entry point
    AVCFPlayerAppliesMediaSelectionCriteriaAutomaticallyKey could not

    I went back to apple website to reinstall iTunes, first reinstalled it same again, then unsinstalled it and the reinstalled it, same again.
    The same thing happened with my old lap top and I replaced it with this new one at the start of the week.
    Has anyone any idea what is going on and how to rectify this problem, I am now going on 3 weeks without iTunes.

    I have been given a new ipod nano to replace my much loved but old ipod. When I plug it into my laptop to sync it I get an error message stating "itunes.exe - entry point not found. The procedure entry point AVCFAAssetCreateWithByteStreanAndOptions could not be located in the dynamic link library

    Also I now can`t access any of my itunes library and am concerned that if I remove it from my computer I will lose everything as I have no option of accessing and therefore backing anything up. Any ideas?

  • Updated to 10.5 on XP and now iTunes will NOT open - Entry Point Not Found - HELP!

    Tried to update to iTunes 10.5 on Windows XP.  Everything seemed to install properly and I restarted.  However, when I try to open iTunes, it will not open and I get the following error message:
    iTunes.exe - Entry Point Not Found
    'The procedure entry point AVCFAssetClassWithByteStreamAndOptions coulf not be located in the dynamic link library AVFoundationCF.dll'
    When I click 'OK' (which is the only option), it says:
    'iTunes was not installed correctly.  Please reinstall iTunes.
    Error 7 (Windows error 127)'
    I have updated iTunes on my machine in the past numerous times without ever having an issue.  Now, I get this and cannot access iTunes at all.  I have tried reinstalling 10.5 and restarting my machine about five times now...to no avail.  I am hesitant to remove iTunes, since I have 6000 songs and do not want to lose my library.  Is there anything I can do?  Seems like it should be a simple fix.
    When I called Apple, they told me to upgrade my OS to Vista.  Huh?  That seems like overkill to me.  iTunes has always run fine on XP.
    Please help!

    I found another site and it suggested that I go through System Preferences and check downloads again.  The iTunes update was still there indicating that it still needed to be downloaded.  So I downloaded it again and now it works fine.  I hope this might help someone else.
    Thank you

  • Entry point not found - iTunes 10.7 for Windows (64-bit) reinstall

    After ignoring iTunes update prompts for about 2 years, I recently tried updating to the latest version (12.1) without success.  After searching for solutions to this problem online, I decided to uninstall iTunes and try reverting back to iTunes 10.7 for Windows 64-bit (on my Windows Vista laptop).
    At this point I have installed, repaired, uninstalled, reinstalled, and repaired the 10.7 version and am still unable to access iTunes.  When I try to launch iTunes, I get the following error messages:
    "iTunes.exe - Entry Point Not Found
    The procedure entry point CMTimeRangeMakeFromDictionary could not be located in the dynamic link library CoreMedia.dll."
    When I click OK, I then get:
    "iTunes was not installed correctly.  Please reinstall iTunes.
    Error 7 (Windows error 127)"
    (As I stated above, reinstalling hasn't worked!)
    In my online troubleshooting searches, I've found posts regarding entry point issues but none with "CMTimeRangeMakeFromDictionary" or "CoreMedia.dll" in them.  I'm unsure what to do next (should I attempt iTunes 12.1 again?), and my biggest concern is that I will somehow lose all my music.  Any help would be greatly appreciated!  Thank you

    Entry point errors can often be fixed by deleting the offending dll, then repairing the component it is part of. CoreMedia.dll is part of Apple Application Support.
    For general advice see Troubleshooting issues with iTunes for Windows updates.
    The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down the page in case one of them applies.
    Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.
    If the advice above doesn't resolve things you could try this alternate version:
    iTunes 12.1.0.71 for Windows (64-bit - for older video cards) - itunes64setup.exe (2015-01-28)
    which is a 64-bit installer for the 32-bit version of the core application, similar to previous 64-bit releases.
    Or roll back to the previous build:
    iTunes 12.0.1.26 for Windows (32-bit) - iTunesSetup.exe (2014-10-16)
    iTunes 12.0.1.26 for Windows (64-bit) - iTunes64Setup.exe (2014-10-16)

  • Itunes 11 will not open itunes.exe entry point not found

    iTunes.exe - Entry Point Not Found
    The procedure entry point kCVKmageBufferChromaSubsampling_420 could not be located in the dynamic link library CoreVideo.dll
    When I click ok another message box shows up:
    iTunes
    iTunes was not installed correctly. Please reinstall iTunes.
    Error 7 (Windows error 127)
    I redownloaded itunes directly from apple.com. I clicked on the repair option. It completed. The error is still happening. I have been using itunes for over 10 years with no problems until now.
    PC info:
    Windows 7 32bit service pack 1 x86
    3GB ram
    AMD Athlon 64 processor 3500+ 2.20 GHz
    NVIDIA GeForce 210 video card 2.2 GB
    Also I used the Firefox browser to download itunes.

    update:
    I just restarted my computer. Now it seems to be working fine. Next time I update itunes I'll just restart my computer twice.

  • ITunes.exe - Entry Point Not Found itunes will install but wont run!!!!!!!!

    I updated itunes and it wont work. i unistalled all apple apps, about 5 to 10 times. i get this message on my HP 530,32 bit windows vista. At the top in the error window it says
    *iTunes.exe - Entry Point Not Found* Then under that in the error box it says:
    *The procedure entry point*
    *QTCF_CFUniCharGetUnicodePropertyDataForPlane could not be located in the dynamic link library QTCF.dll.*
    What do i DO PLEASE HELP ME OUT!!!!!!!!

    I found the qtcf.dll file in the sys32 moved it to the desktop tried iTunes and still same error message as above.
    Okay ... sometimes there can be multiple copies of them lurking about on a PC.
    Try heading into Computer, and typing QTCF.dll in your Search field. When Vista tells you it can't find the file, click "advanced" and tick the "Search hidden, non-indexed and system files (might be slow)" and then start another search.
    This search *will indeed be slow.* Wait until the green progress bar up at the top of the screen has completely vanished, otherwise you might accidentally stop the search too soon.
    What copies of QTCF.dll do you find, and where are their file locations? (The default location on a 32-bit Vista PC is in C:\Program Files\QuickTime\QTSystem\QTCF.dll)

  • Error: iTunes.exe Entry Point Not Found

    "iTunes.exe - Entry Point Not Found
    The procedure entry point kCMByteStreamNotification_AvailableLengthChanged could not be located in the dynamic link library CoreMedia.dll."
    and when I click ok it then gives me this error message

    I have tried the following several times:
    reinstalled/repaired iTunes
    reinstalled/repaired QuickTime
    reinstalled/repaired Apple Software Update
    reinstalled/repaired Apple Application Support
    none of which have worked.  I get the error each time i try to open iTunes and then it just shuts down.
    I have also tried to open iTunes in safe mode - per a recommended solution on another thread - which does not work.  And I changed my control panel/quicktime/audio settings to safe mode - per a recommended solution on another thread - which does not work.
    I have not added any other new software
    I am on an old lenovo T61 laptop with Windows XP

  • Locked iTunes folder & 'AppleSyncNotifier.exe – Entry Point Not Found'

    Below message seen on log in on a Windows 7 laptop, even after a full reinstall.:
    "AppleSyncNotifier.exe – Entry Point Not Found
    The procedure entry point xmlTextReaderConstName could not be located in the dynamic link library libxml2.dll"
    In case it's related, soon after, when trying to run iTunes, it failed with a 'no such .exe' type message. Itunes.exe had gone.
    After saving the user iTunes library tree, I installed a fresh uptodate iTunes which failed because one of the iTunes subfolders, iTunes.Resources, would not let itself be deleted, not even when on the Administrator account.  Solved this by installing in a slightly-differently named iTunes folder, of course.
    How the above DLL survived the reinstall, I don't know.  Is there any brutish way that I can nuke the original iTunes folder's remains?

    I'd first try uninstalling and reinstalling your MobileMe control panel.

  • My iTunes won't open on Windows XP. iTunes.exe - Entry point not found, Error 7 (Windows Error 127)

    When I open iTunes, I get a message saying under iTunes.exe - Entry Point Not Found, it says, The procedure entry point sqlite3_wal_checkpoint could not be located in the dynamic link library SQLite3.dll. And I'm not talking about the AppleSyncNotifier.exe. Along with that, I get the message saying, "iTunes was not installed correctly. Please reinstall i Tunes." Error 7 (Windows Error 127). That's why I'm unable to open iTunes. I sure hope to see a solution to those problems soon.
    I know I've mentioned this before, but I've now given a little more info to make my explanation more clear.

    Hi
            I have tried to research these problems I am getting, but have not been able to resolve them.
    1st is the above DDE Server Windows iTunes.exe - entry point not found.
    This only occurs when I try to start iTunes.
    if I click ok , several times, iTunes will start but slowly.
    If at any time I have to reboot my computer I get
    iTunesHelper.exe - the procedure entry point asl_add_log_file could not be located in the dynamic link library ASL.dll
    if I click 3 times OK it goes away.
    To this end I have uninstalled iTunes and rebooted my machine then gone to iTunes web site and downloaded the latest version.
    Installing it but still get the same errors on reboot and trying to run iTunes
    Anyone any ideas please.

    Taken at face value, you're having trouble with an Apple Application Support program file there. (Apple Application Support is where single copies of program files used by multiple different Apple programs are kept.)
    Let's try something relatively simple first. Restart the PC. If you're using Vista or 7, now head into your Uninstall a program control panel, select "Apple Application Support" and then click "Repair". If you're using XP, head into your Add or Remove Programs control panel, select "Apple Application Support", click "Change" and then click "Repair".
    If no joy after that, try the more rigorous uninstall/reinstall procedure from the following post. (If you've got XP, although the procedure is for Vista and 7, just read "Computer" as "My Computer", read "Uninstall a program control panel" as "Add or Remove programs control panel" and assume the system is 32-bit, and you'll be doing the right things.)

  • After downloading the latest version of iTunes and updating my iPhone everytime I turn on my computer I get a message that reads: AppleSyncNotifier.exe - Entry Point Not Found. Does anybody know what this means?

    After downloading the latest version of iTunes and updating my iPhone, everytime I turn on my computer I receive a message that reads: "AppleSyncNotifier.exe - Entry Point Not Found. The procedure entry point sqlite3_wal_checkpoint could not be located in the dynamic link library SQlite.dll" Help! Does anybody know what this means and how I can fix it? Thanks.

    Yes.  I just solved the problem on my PC.  Here goes...
    Issue:  My Windows7 computer was producing the pop up box with the error text as you described.
    The Problem: You have another application on your computer that uses the like named .DLL file... in this case a DLL supporting SQLite on your local PC.
    Solution: 
    1.  You need to use the Windows File search feature to look for the name "SQLite".  This will quickly locate the offending DLL in the other application.
    2. Decide which program you like the most, in my case "Mobile Me", and uninstall the offending application.
    3.  Uninstall Mobile Me.
    4.  Restart your PC.
    5.  Reinstall Mobile Me.
    6.  Mobile Me should sync at this point, but if not, restart the PC once again.
    In my case, the offending program was my Aptana Studio development application.  I had recently the SQLite3 database to my Ruby On Rails configuration...
    This is where the file was located:
    C:\Users\<USERNAME>\Aptana Studio 2.0\plugins\com.aptana.radrails.sqlite3.win32_3.5.7.1278709071\vendor\SQLite3.d ll
    I hope this helps,
